Grass Snake (Natrix natrix)

Adult Grass Snake (subspecies N. n. helvetica) at Geddington, Northants - August 2008

OTHER NAMES: Common Snake, Green Snake, Water Snake, Ringed Snake
Featured Subspecies: Natrix natrix helvetica
Weight: 240g
Length: 100cm
NOT EVALUATED IUCN Red List: Least Concern

The largest land based reptile in the UK, grass snakes are also by far the commonest of the UKs three native snake species  - it isn't technically particularly rare but seeing even this most common of snakes is a rare and unusual occurrence, which in most places isn't at all reliable.  It is not venomous, and mainly eats frogs and toads - and is also known as the water snake for it's propensity for swimming - often catching tadpoles. It may occasionally, as in this case, enter gardens and even hibernate or breed in people's compost heaps.
